The Royal Couple Share Their First Public Kiss (VIDEO)

Prince William and Kate Middleton, who are now officially the Duke and Duchess of Cambridge, stood on the balcony of Buckingham Palace and shared their first public kiss as husband and wife.

The long-awaited public display of affection was quick -- blink and you miss it -- and was watched upon by thousands of people gathered outside the palace's gates, who cheered when the appeared from behind the glass doors.

Prince William is notoriously shy when it comes to PDA (unlike his little brother Harry) and the crowd chanted "Kiss her again!" So he did. The newlyweds shared not one but two kisses in front of the adoring public.

The rest of the wedding party, including the Queen, the Middleton family, and Prince Charles and Camilla Bowles watch on as the Royal Air Force and Battle of Britain Memorial Flight flew over the celebratory crowd.
